XYZ options.

Name Type Description
attributions Array.<ol.Attribution> | undefined

Attributions.
crossOrigin null | string | undefined

The crossOrigin attribute for loaded images. Note that you must provide a crossOrigin value if you are using the WebGL renderer or if you want to access pixel data with the Canvas renderer. See https://developer.mozilla.org/en-US/docs/Web/HTML/CORS_enabled_image for more detail.

Optional max zoom level. Default is 18.
minZoom number | undefined experimental

Unsupported (TODO: remove this).
tileLoadFunction ol.TileLoadFunctionType | undefined experimental

Optional function to load a tile given a URL.
tilePixelRatio number | undefined experimental

The pixel ratio used by the tile service. For example, if the tile service advertizes 256px by 256px tiles but actually sends 512px by 512px images (for retina/hidpi devices) then tilePixelRatio should be set to 2. Default is 1.
tileSize number | ol.Size | undefined experimental

The tile size used by the tile service. Default is [256, 256] pixels.
tileUrlFunction ol.TileUrlFunctionType | undefined experimental

Optional function to get tile URL given a tile coordinate and the projection. Required if url or urls are not provided.
url string | undefined

URL template. Must include {x}, {y} or {-y}, and {z} placeholders.
